Phase transitions in M(ClO4)2.6H2O (M = magnesium, zinc). Investigations by adiabatic calorimetry and infrared spectroscopy.
IR spectra of Mg(ClO4)2.6H2O at 10 K indicate a complex structure contg. at least 16 distinct types of H2O protons. At 107.9 K this structure transforms sharply to a much simpler disordered form (?Strans = 7.754 J K-1 ... -
Phase transitions in metal perchlorate hydrates: the supposed hydrate-to-pseudohydrate transformations.
A polemic. The hydrate-to-pseudohydrate transformations in metal perchlorate hydrates reported by M. B. Patel and H. D. Brist (ibid. 1983, 79, 4489) and Solid State Commun. (48, 139 (1983)) as well as the suggested ... -

Phenolic Resin as an Inexpensive High Performance Binder for Li-Ion Battery Alloy Negative Electrodes
Phenolic resin was evaluated as a binder material for Li-ion battery negative electrodes containing Si-based alloys. Phenolic resin was found to have a large first lithiation capacity of about 1200 mAh/g, which is suspected ... -
Phonon dispersion and Gruneisen parameters of zinc dicyanide and cadmium dicyanide from first principles: Origin of negative thermal expansion.
Zinc dicyanide, Zn(CN)2, and the isostructural cadmium dicyanide show neg. thermal expansion over a broad range of temps. By the use of d. functional theory calcns., we det. the phonon dispersion curves of these materials ... -
Photo-induced Anticancer Activity and Singlet Oxygen Production of Prodigiosenes
The photo-induced cytotoxicity of prodigiosenes is reported. One prodigiosene represents a synthetic analogue of the natural product prodigiosin, and two are conjugated to molecules that target the estrogen receptor (ER). ... -
Photoacoustic Investigation of the Temperature and Magnetic-Field Dependence of the Specific-Heat Capacity and Thermal-Conductivity Near the Curie-Point of Gadolinium
The photoacoustic technique was used as a simple but accurate tool to simultaneously determine the specific-heat capacity C and thermal conductivity kappa of gadolinium in the neighborhood of the Curie point. One ... -
The Photodecarboxylation of Substituted Naphthylmethyl Arylacetate Esters: Synthesis of Naphthylarylethanes
The synthesis of naphthylarylethanes via the photodecarboxylation of naphthylmethyl arylacetate esters is reported where the aryl group is able to stabilize a charge transfer reaction. The reaction proceeds via intramolecular ... -
Polyaniline Electrode Activation in Li Cells
Polyaniline (PANi) can be used as an electroactive organic cathode material in Li-cells with multiple redox states. The theoretical specific capacity of the emeraldine base (PEB) is 150 mAh g−1. In this study, we show how ... -
